Jacaranda mimosifolia
Also called Blue Brazilian, Brazilian Rosewood, Fern Tree, Blue Jacaranda, Jacaranda
Black poui (Jacaranda mimosifolia) is a subtropical tree from South America, grown for its violet-blue spring flowers and fern-like leaves. It needs full sun, well-drained soil and a frost-free climate to thrive.
Jacaranda mimosifolia is a sub-tropical tree native to south-central South America that has been widely planted elsewhere because of its attractive and long-lasting violet-colored flowers. It is also known as the jacaranda, blue jacaranda, Nupur or black poui. Older sources call it J. acutifolia, but modern authorities usually classify it as J. mimosifolia. In scientific usage, the name "jacaranda" refers to the genus Jacaranda, which has many other members, but in horticultural and everyday usage, it nearly always means the blue jacaranda.
In its native range in the wild, J. mimosifolia is listed as Vulnerable by the IUCN.
Jacaranda trees were introduced to South Africa by Baron von Ludwig during the start of the botanical garden in Cape Town around 1829. Pretoria, the administrative capital of South Africa, is popularly known as Jacaranda City because of the large number of trees; It is estimated that Pretoria and surroundings are home to more than 65,000 of them. Jacaranda trees turn the city blue and purple when they flower in spring. The jacaranda trees, far from their native South Central South America (southern Brazil, Paraguay, northern Argentina, and southern Bolivia), bloom every October. Water scarcity has South Africa trying to eradicate foreign species of plants and trees, including the jacaranda. Acknowledging the tree's popularity with locals, the government announced in the early 2000s that it would not remove the trees, but banned the planting of new ones. By 2016, this decision was reversed, and jacarandas were again allowed to be planted in urban environments in some provinces.
The first jacaranda bloomed in Sydney, Australia, in about 1850.
Jacaranda mimosifolia is native to southern Brazil, Uruguay, Paraguay, northern Argentina (Salta, Jujuy, Catamarca, and Misiones provinces), and southern Bolivia. It is found in the Dry Chaco and flooded savannas, and in the Southern Andean Yungas of the eastern Andean piedmont and inter-Andean valleys, up to 2600 meters elevation. In its native range, the tree is threatened by uncontrolled logging and clearing of land for agriculture, and is assessed as Vulnerable in the IUCN Red List.
